Jock Stein
Jock Stein was the first manager to win the European Cup with a British side, securing an unforgettable triumph with Celtic in 1967.
That side—the Lisbon Lions—were all born within a 30-mile radius of Glasgow, and remain the greatest-ever Celtic XI.
They stood out both for their homegrown identity and for their bold attacking football; indeed, the Buoys overcame the great Internazionale—the greatest proponents of catenaccio.
Stein would be a purist’s delight—both promoting youth and local players to the first team, and not folding in the face of boring, negative football—another rival for Jose, perhaps?
